The main component of bauxite ore is alumina, which is a hydraulic aluminum, which is a kind of earth-shaped mineral. White or gray-white, brown yellow or light red due to iron. Involved in water, can be dissolved in sulfuric acid and sodium hydroxide solution. Bauxite ore is mainly used for aluminum refining and refractory materials. Bauxite ore is generally formed by chemical weathering or exogenous effects. There are few pure minerals, always containing some impurities minerals, more or less containing clay minerals, iron minerals, titanium minerals, and debris heavy minerals.
1. The aluminum editing industry. Used for national defense, aviation, automobiles, electrical appliances, chemicals, daily life supplies, etc.
2. Precision casting. The bauxite ore is processed into a fine powder and made into casting. Used for military industry, aerospace, communication, instrumentation, machinery, and medical device departments.
3. Used for refractory products. The refractory resistance of bauxite ore is as high as 1780 ° C. It has strong chemical stability and good physical properties.
4. Used for aluminum refractory fiber. Bauxite ore has the advantages of being lightweight, having high-temperature resistance, good thermal stability, low thermal conductivity, small heat capacity, and mechanical vibration. Aluminum ore is used for steel, non-ferrous metallurgy, electronics, petroleum, chemical, atomic energy, national defense, and other industries. It can be pressed into fibrous blankets, plates, or weaving cloth instead of refractory tiles lined with the industrial high-temperature kiln in industrial high temperature. Firefighters can make clothes with a refractory fiber cloth.
5. Consolidated by magnesium and alum soil clinkers, adding appropriate binding agents to pour the overall barrel lining of the steel barrel is very good.
6. It has various compounds of aluminum cement, grinding materials, ceramic industries, and chemical industries.
